The QS3245 provides a set of eight high-speed CMOS TTL-compatible bus switches in a pinout compatible with 74FCT245, 74F245, 74ALS/AS/ LS245 8-bit transceivers. The low ON resistance of the QS3245 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. The QS3245 operates at -40C to +85C.

The QS3251 is a high-speed CMOS TTL-compatible 8:1 multiplexer/demultiplexer that has 3-state outputs. The QS3251 is a function and pinout-compatible version of the 74F251, 74FCT251, and the 74ALS/AS/LS251 8:1 multiplexers. The low ON-resistance of the QS3251 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. Mux/Demux devices provide an order of magnitude faster speed than equivalent logic devices. The QS3251 is characterized for operation at -40 °C to +85 °C.

The QS3253 is a high-speed CMOS TTL-compatible dual 4:1 multiplexer/demultiplexer with 3-state outputs. The QS3253 is a function and pinout-compatible version of the 74F253, 74FCT253, and 74ALS/AS/LS253 dual 4:1 multiplexers. The low ON-resistance of the QS3253 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. The QS3253 operates at -40 °C to +85 °C.

The QS32X2384 provides a set of twenty high-speed CMOS TTL-compatible bus switches. The QS32x2384 also includes internal 25 ohm series termination resistors to reduce reflection noise in high-speed applications. Four Bus Enable signals are provided, one for each of five bits of the 20-bit bus. The QS32X2384 is ideal for switching wide digital buses, as well as hotplug buffering, and 5V to 3V conversion. The QS32X2384 operates at -40C to +85C.

The QS32X245 provides a set of 16 high-speed CMOS TTL-compatible bus switches in a flow-through pinout. The low ON-resistance of the QS32X245 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. QuickSwitch devices provide an order of magnitude faster speed than conventional logic devices. The QS32X245 operates at -40 °C to +85 °C.

The low ON resistance of the QS32X384 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. Four Bus Enable signals are provided, one for each of five bits of the 20-bit bus. The QS32X384 is ideal for switching wide digital buses, as well as hotplug buffering, and 5V to 3V conversion. The QS32X384 operates at -40C to +85C.

The QS32XVH384 HotSwitch is a high bandwidth, 20-bit bus switch with very low ON-resistance, resulting in under 250ps propagation delay through the switch. Four banks of five switches are controlled by independent (xOE), LVTTL-compatible signals for bidirectional data flow with no added delay or ground bounce. The combination of near-zero propagation delay, high OFF impedance, and overvoltage tolerance makes the QS32XVH384 ideal for high-performance communications applications. The QS32XVH384 operates from -40 °C to +85 °C.

The QS3306A provides a set of two high-speed low resistance (3Ω typical) CMOS switches connecting inputs to outputs without propagation delay and without generating additional ground bounce noise. Individual enables (OE) are used to turn on the switches. The QS3306A is ideal for signal and control switching since the device adds no noise, ground bounce, propagation delay, or significant power consumption to the system. The QS3306A can also be used for analog switching applications such as video. The QS3306A operates at -40 °C to +85 °C.

The QS3383 provides ten high-speed CMOS TTL-compatible bus switches. The low ON-resistance of the QS3383 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. Bus exchange configuration allows byte swapping of buses in systems. It can also be used as a 5-wide 2-to-1 multiplexer and to create low-delay barrel shifters, etc. The QS3383 operates at -40 °C to +85 °C.

The QS3384 provides a set of 10 high-speed CMOS, TTL-compatible bus switches. The low ON-resistance of QS3384 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce. Two banks of five switches are controlled by independent Bus Enable (BE) signals. The QS3384 operates at -40 °C to +85 °C.
